"Electrodynamic Vibrator Compressor".

The invention relates to an elliptical Koairressor.

The press chamber with the enclosed valve eye system on its side forms a part of the l'eaten. The silk β inu are connected to one another by one or more Pederti and the movable mass is set in a reciprocating motion at the frequency of the echaelBtromea to be fed to the current coil,

where the natural frequency of the shrinking system "" is set in such a way v, ird, " that this is close to the current frequency.

In most applications, namely τ; βήη the Kocipressor for Compressing the Kuhlir. By means of a KompresserkühlsehreiikeE serves, should "' As little vibration forces as possible on the housing via the support element. ', and it is already known to use coil springs for this purpose which between the end walls of the housing and the fixed seat of the vibrator are appropriate.

In practice, an arrangement of the vitrator-compressor is required in which the longitudinal axis extends vertically, and even then the housing must have a comparatively large diameter, because the vibrator system cannot be kept in the centered position during operation can. Also ITIT in the known devices use comparatively long springs required, a & xit de U * = transmission of vibrations to the housing e ± \ can be ective fcintanerelialteii.

The invention aims to eliminate the disadvantages and is characterized in that the elasticity of the latter Spring system essentially in the direction of the motion beams Compressor pistons are limited as the spring syste »in one sighting is rigid across this path.

In these heads, these bodies are disc-shaped so that they have great rigidity in a direction perpendicular to the axis 8 and thus to the direction of movement of the oscillating system, whereby a good centering of this axis is obtained with respect to the housing 17 and the housing engsehlies & end can be attached around the compressor, so that it takes up little space in the ..uperriuhtung. In the axis alignment, however, the transmission of vibrations from the compressor to the housing is almost completely avoided by the fact that the spring bodies , as shown in FIGS. corrugated membrane are formed.

It can also be stated that this spring body is in Direction of the axis 8 have a very narrow dimension, so that in in this direction the dimensions of the housing can be further reduced can.

It can be seen from FIGS. 4 and 5 that, instead of a disk-shaped suspension spring, a leaf spring 23 could also be used, the ends of which could be slidably inserted into slots of supports (not shown) attached to the wall of the housing 17; one leg of a bow-shaped leaf spring 24 (FIG. 5) could also be ^{attached to a} "der" / and of the housing, while the other leg is a rod oriented along the axis of the housing 17! 18 or 19, of the compressor in an opening 25 carries.

It is also possible to use spring bodies which consist of Guicmib blocks, which have such a configuration or which are enclosed in such a way that the elastic deflections in two mutually perpendicular directions are very different.
